3The Youden index was used as a cutoff value for discriminating CIMP-positive ccRCCs in the learning cohort from CIMP-negative ccRCCs. When the cancerous tissue shows a DNA methylation level equal to or higher than the cutoff value, the ccRCC is considered to be CIMP-positive; when the cancerous tissue shows a DNA methylation level lower than the cutoff value, the ccRCC is considered to be CIMP-negative.
